tal stabilizer also contains the elevator trim tab actuator. Construction of
the elevator consists of formed leading edge skins, a forward spar, ribs,
torque tube and bellcrank, left upper and lower "V" type corrugated skins,
and right upper and lower "V" type corrugated skins incorporating a
trailing edge cut-out for the trim tab. The elevator trim tab consists of a
spar and upper and lower "V" type corrugated skins. Both elevator tip
leading edge extensions incorporate balance weights.
FLIGHT CONTROLS
The airplane's flight control system (see figure 7-1) consists of
conventional aileron, rudder, and elevator control surfaces. The control
surfaces are manually operated through mechanical linkage using a
control wheel for the ailerons and elevator, and rudder/brake pedals for
the rudder. The elevator control system is equipped with down springs
which provide improved stability in flight.
Extensions are available for the rudder / brake pedals. They consist of a
rudder pedal face, two spacers and two spring clips. To install an exten-
sion, place the clip on the bottom of the extension under the bottom of the
rudder pedal and snap the top clip over the top of the rudder pedal. Check
that the extension is firmly in place. To remove the extensions, reverse the
above procedures.
TRIM SYSTEMS
Manually-operated rudder and elevator trim is provided (see figure 7-
1). Rudder trimming is accomplished through a bungee connected to the
rudder control system and a trim control wheel mounted on the control
pedestal. Rudder trimming is accomplished by rotating the horizontally
mounted trim control wheel either left or right to the desired trim position.
Rotating the trim wheel to the right will trim nose-right; conversely
rotating it to the left will trim nose-left. Elevator trimming is accomp-
lished through the elevator trim tab by utilizing the vertically mounted
trim control wheel. Forward rotation of the trim wheel will trim nose-
down; conversely, aft rotation will trim nose-up. The airplane may also be
equipped with an electric elevator trim system. For details concerning this
system, refer to Section 9, Supplements.
INSTRUMENT PANEL
The instrument panel (see figure 7-2) is designed around the basic "T"
configuration. The gyros are located immediately in front of the pilot, and
